Routing method of content-centric network strategy layer

Abstract

The invention discloses a routing method of a content-centric network strategy layer. The method comprises the following steps of: respectively determining data transmission round-trip time, transmission rate and energy consumption of each network interface according to history states of forwarding data of n network interfaces; computing the energy consumption cost according to the determined the data transmission round-trip time, transmission rate and energy consumption of each network interface; and computing the minimum energy consumption cost under the limitation of the round-trip time, and forwarding interest packets by selecting k former interfaces with largest forwarding probability when the energy consumption cost is minimum, wherein the k is less than n. According to the states of a plurality of internet interfaces of equipment, the optimum network interface can be automatically selected for forwarding the interest packets, so as to forward the interest packets by the plurality of interfaces and realize multisource acquisition, thus avoiding interface failure brought by movement, improving the data forwarding mobility and reliability, and optimizing equipment forwarding property.

Description

technical field [0001] The invention relates to the technical field of computer architecture, in particular to a routing method for a content-centric network strategy layer. Background technique [0002] With the continuous development and changes of Internet applications, the existing Internet based on TCP / IP has gradually exposed many problems, such as poor security, no mobile support, poor reliability, lack of flexibility, limited effectiveness, and rigidity to new applications. Aiming at these problems, many research institutions at home and abroad are currently designing and researching the architecture of future networks. [0003] Content Centric Networking (CCN) is one of the important results of the current future Internet architecture research. Its core idea is to change the current end-to-end communication mechanism between Internet terminals, separate the content from the terminal location, and publish / subscribe Paradigm (Publish / Subscribe Paradigm) to provide se...

Problems solved by technology

In order to ensure the forwarding of interest packets of these mobile devices, it is difficult to guarantee the reliability of a single interface

[0008] At the same time, due to the size of the power module of the mobile device, the energy consumption limit is also obvious, so the network transmission is restricted by the energy consumption, and the improvement of the network throughput also means the intensification of the energy consumption.
